The so-called automatic transmission, as the name suggests, does not require the driver to manually shift gears, the vehicle will automatically select the appropriate gear according to the speed of travel and traffic conditions.

Since the design of the automatic software program is complex and varied, the automatic transmissions on different models will have different driving sensations and driving methods. However, there are some common features between them, and they will be introduced one by one. Forced downshift with the O/D block switch In order to pursue the low speed of the manual wave, we can also use the O/D block switch in the automatic stop to force the downshift. Some people may ask, what if you don't have an O/D switch and need to accelerate the car quickly? Don't forget, the automatic transmission also has a Kick-down function, which is to quickly step on the throttle. In the open position, the transmission will automatically lower the first gear to achieve a more enhanced acceleration. It should be noted that under the Kick-down condition, the friction and friction of the friction plate in the automatic transmission are serious, which may cause chipping or bonding, and should be used as little as possible. If you are born to be a speed enthusiast, especially if you want to have the most violent acceleration in the automatic traffic, you can also use a shifting method similar to the hand-held car, that is, the bar is started by pressing 1, 2 3, D sequence shift, when you see the tachometer approaching or reaching the red zone, immediately hang into the high gear, so that you can make full use of the engine's power to achieve the fastest acceleration. In fact, this is a way to use the gears of automatic transmission cars 1, 2, 3, etc. In addition, these gears can also act as a brake when going downhill. However, when using these gears for braking, it is necessary to make the vehicle speed lower than the upshift speed of the gear during normal driving, otherwise the corresponding low-speed actuator will be damaged due to sharp friction, increasing the cost of use. . When using the low-speed gear to open the automatic car in time, when the D-stop is driving on the ramp, the speed will decrease due to the large resistance. When the speed is reduced to a certain speed, the automatic transmission will automatically reduce the first gear, and then the driving force is greater than the resistance. Accelerate, and when it rises to a certain speed, it rises to the first gear. If the slope is long enough, the transmission will be jumped back and forth between the two gears to form a "frequent jump", which will aggravate the wear of the friction plates in the automatic transmission. At this time, the driver needs to select one of the appropriate gears of L, 1, 2, and 3 according to the magnitude of the slope and the road condition, so that the transmission is always stable in this gear. In fact, this is one of the most important reasons for setting the gears of L, 1, 2, 3, etc. It is also a way to force the gear to lock. Under normal circumstances, if there is no special requirement during driving, do not move the lever in the D, 3, 2, 1 and other gears. It is especially forbidden to shift the lever into the N range during driving or to use the N position when going downhill. Otherwise, due to the idle running of the engine, the oil supply in the engine-driven transmission is reduced, resulting in parts in the automatic transmission. Poor lubrication and damage. Fuel saving can be increased in advance to save fuel. In addition to using the selected economic mode described above, the method of “advance upshift†can also be adopted. After the car starts, the car is quickly added to a certain speed with a larger throttle, and then The throttle is quickly released and held for two or three seconds, at which point the automatic transmission can immediately rise from first to second. When you feel the upshift, press the throttle to continue to accelerate, and other gears can also use this method. This kind of operation not only saves fuel, but also reduces noise and reduces engine wear. It is a driving method that should be widely promoted. Another feature of the car equipped with an automatic transmission is that after the engine is started, no matter if the lever is placed in any travelable position, as long as the brake and the hand brake are released, the car will slowly start itself even if the throttle is not stepped on. This is the "creep phenomenon" unique to automatic transmissions, which is one of the characteristics of automatic transmission vehicles. Therefore, when driving an automatic transmission, it must be noted that when the engine is just started (high frictional resistance) or when the air conditioner is being used, due to the faster engine speed, it will cause strong creep phenomenon. At this time, the foot brake should be especially careful. Can not be too loose, so as not to cause an accident. To know how to collect oil, whether it is automatic or manual, it is necessary to refuel on the highway. However, in the urban area, the automatic control and automatic manual transmission, the throttle control method is completely different. No matter how fast or how slow, open manual gear is to add oil to maintain the speed; but in the urban area to open the automatic block, in addition to acceleration, most of the time should be oil. In the urban area where the traffic lights are everywhere, if you are driving like a manual car, you will close the brakes when you get close to the front car. Your fuel consumption and brake pad loss must be very serious. The person sitting in your car will not be comfortable. I even think that your driving skills are really flattering. Therefore, in order to save yourself fuel, save maintenance costs; in order to let others feel that your driving skills are skilled; in order to drive comfort, open the automatic car can see the red light after the far-off.
